1957 Ford F-100 - not so popular?

I just spent the week at Barrett Jackson, in part, to learn about the classic truck and classic custom truck market. There were alot of early 50s Ford's and Chevy's. What I thought was interesting was how popular the 1955 and 1958 Chevy Cameo was compared to Ford's similar body style of the 1957 F-100. It does not seem like Ford's new 57 design caught on quite the way Chevy's cameo did. Any thoughts on this? Also, when I search for 1957 F-100's they seem to be few and far between? Where did they all go?
